Logitech Noise Canceling Headphones
Bought these for my husband who is a frequent work traveler. Tested these with the garbage disposal on --- I really could not hear it! Great product but long wait time to order online.
Give mom the gift she's probably been desiring since you were born - quiet.
The open-air design provides listening comfort and the folding headband is compact for travel. Built-in microphones sense outside noise and send an equal-but-opposite canceling signal to the headphones, reducing ambient noise.
The people around my cubicle like to talk and laugh and do imitations, that's why I thank gawd every day for my noise-canceling ear buds. Just jam them in my ears and I can't hear a thing other than sweet music.
